Compartmentalized 3D Tissue Culture Arrays under Controlled Microfluidic Delivery
We demonstrate an in vitro microfluidic cell culture platform that consists of periodic 3D hydrogel compartments with controllable shapes. The microchip is composed of approximately 500 discontinuous collagen gel compartments locally patterned in between

Ruthenium Oxide pH Sensing for Organs-On-Chip Studies
A ruthenium oxide (RuOx) electrode is being developed as potentiometric pH sensor for organs-on-chip applications. Open-circuit potential (OCP) of the RuOx electrode showed a response of −58.05 mV/pH, with no cross-sensitivity to potentially ...

Online monitoring of biofouling using coaxial stub resonator technique
Here we demonstrate the proof-of-principle that a coaxial stub resonator can be used to detect early stages of biofilm formation. After promising field tests using a stub resonator with a stainless steel inner conductor as sensitive element, the ...

High-resolution and multi-range particle separation by microscopic vibration in an optofluidic chip
An optofluidic chip is demonstrated in experiments for high-resolution and multi-range particle separation through the optically-induced microscopic vibration effect, where nanoparticles are trapped in loosely overdamped optical potential wells created ...

Nanofluidics in Lab-on-a-Chip Devices [PDF]
As the field of nanofluidics matures, fundamental discoveries are being applied to lab-on-a-chip analyses. The unique behavior of matter at the nanoscale is adding new functionality to devices that integrate nanopores or nanochannels. (To listen to a podcast about this feature, please go to the Analytical Chemistry website at pubs.acs.org/journal ...

Electrofusion of single cells in picoliter droplets
We present a microfluidic chip that enables electrofusion of cells in microdroplets, with exchange of nuclear components. It is shown, to our knowledge for the first time, electrofusion of two HL60 cells, inside a microdroplet.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Predicting Dimensions in Microfluidic Paper Based Analytical Devices
The main problem for the expansion of the use of microfluidic paper-based analytical devices and, thus, their mass production is their inherent lack of fluid flow control due to its uncontrolled fabrication protocols.
